Nothing to brag about per say, but I am very happy with the outcome of this project and can now leave well enough alone and focus on the STi..until I break something that is (). Thank you, as always, to the great crew at Surgeline for another fantastic job and stellar communication along the way.

The car is extremely derivable and compliant. Lance had access to an additional map that was not available when the car was first tuned which directly affects throttle mapping. I can now rev-match easily since a blip on the throttle actually translates into said command in the engine.

thats pretty badass! what a sleeper. vf52s are nice! i upgraded to a vf52 in my 08 wrx a few years back. what a difference over the instant boost td04. nice numbers too!!

Nice work doing that upgrade on your 08'. What the heck they were thinking in 08' I don't know. I am very fond of the VF-52, esp. for a very heavily daily driven car. Moreover, this Outback see many trips loaded with people and gear. The kind of load that generates, esp. maintaining speed over passes, really does not warrant any larger a turbo unless I want to start building other parts of the car. Call me conservative.

There is a guy in TX with an 05' OXT running gobs of power, and think he did a 6-spd swap?

Also, with the re-route EWG, it is about as loud as a short ram. Totally worth the cost.

Great numbers. I am running a similar setup and will be putting a 38mm vband external wastegate uppipe with dump tube in next week due to some boost creep I am experiencing. Do you have a picture of your wastegate set up? Something tells me I will have problems clearing the cat on my CNT downpipe.

That has been my impression of the EWG, esp. re-routed, with the high-up cats. The main reason I changed to the COBB down pipe before doing this all was b/c of the lower cat.

This is a photo of the same set-up on my STi (COBB UP/DP and 44mm EWG). I can take a similar photo of the Outback. Is this what you had in mind for a shot?

Also, i had boost creep as well with the bell mouth COBB which precipitated the EWG.

I think your targeted AFR's are more around 11-11.2 which is right where they should be. If you were targeting 11.6 on pump gas you would be fairly prone to knock events. The chart looks great for a VF52, this must really be a fun grocery getter.

Indeed!

Sorry if my reporting of numbers suck. Obviously you can see the limit of 'tuning mind.'

I just took the car to central OR which meant heading over a small pass via Mt. Hood (like 4000ft+) with 4 people and gear in the car. The car performed great keeping it in the lower boost map. Easing throttle but not being afraid to spool it up everything was very smooth. Never a need for WOT, which I would not want to do since that is tons of load.

It has been a little while now with the current set-up and I wanted to share some observations:

1) The re-routed EWG is very quiet. My wife drives the car most days and has not said a word. There have been no comments from people riding in the car, either. See two below, and the above comments still stand.

2) The tune is fantastic. I took the Outback out to McKenzie Pass for some biking this weekend. Four guys, two bikes up-top, two on the hitch and all our gear and camping stuff. Making load is easy, so it was "S" mode only. By really squeezing the accelerator I could get the car to respond well with power and with good smoothness. The car never felt lacking in the go department including passing. There was no noticeable funny business from the EWG, etc. in modulating power and hence boost as we climbed.

3) The power and tune in conjunction with the changes made to brakes and suspension make the Outback incredibly fun and functional. Even on long road trips there is usually a discussion about who gets to drive...b/c everyone wants to.

4) An LGT was recently tuned on the same dyno with very similar mods and made nearly identical power. Nice to see the consistency:

I have a 05 obxt, with forged internals, and a blouch 20g-xt..etc, etc, but Im looking for a EWG setup as well, what did you choose for a upipe for the setup? I was looking at gtspec maybe. still kinda browsing on options and what I feel like, would also be dumped, not plumbed back in. thanks, derek

I went with the COBB set-up. I re-routed b/c my wife drives that car more than I do and with it re-routed it is no louder than a short-ram. I also don't believe that in my heavy OXT with a vf-52 I would actually notice any power difference between the duped vs. re-routed EWG.

What pushed me to go with an EWG was simply boost control.

Sounds like you got a nice set-up there! You running Outback ride height or did you drop it?
